• Experimental Evaluation of Multi-scale Tactile Maps Created with SIM, a Web App for Indoor Map Authoring

  Viet Trinh, Roberto Manduchi, Nicholas A. Giudice · 2023 · ACM Transactions on Accessible Computing

  This paper introduces Semantic Interior Mapology (SIM), a web application that democratizes tactile map creation by allowing anyone to trace a floor plan image and automatically generate embossable tactile maps at multiple scales. Unlike outdoor environments where services like…

• Uncovering Information Needs for Independent Spatial Learning for Users Who Are Visually Impaired

  Nikola Banovic, Rachel L. Franz, Khai N. Truong, Jennifer Mankoff, Anind K. Dey · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents two studies examining how visually impaired individuals learn about their environments and build cognitive maps — the mental representations of spatial relationships that sighted people largely construct through casual visual observation. Study 1 involved…

• Learning Non-Visual Graphical Information Using a Touch-Based Vibro-Audio Interface

  Nicholas A. Giudice, Hari Prasath Palani, Eric Brenner, Kevin M. Kramer · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper evaluates a vibro-audio interface on a commercial Samsung Galaxy tablet that provides non-visual access to graphical information through synchronized vibration and audio feedback triggered by touch exploration. When users trace their finger over on-screen visual…
